Abstract
Systems and methods for remotely closing a switch that is downhole in a wellbore are disclosed. The switch has a body with a first connector and a movable piston assembly with a second connector configured to mate with the first connector. The piston assembly has a first position wherein the first and second connectors are separated and a second position wherein the first and second connectors are mated. A spring is disposed between the body and the piston assembly and configured to urge the piston assembly toward the first position. When the fluid in the wellbore reaches a pressure above a threshold, the piston assembly will move to the second position thereby closing the switch.
